6 is a detail perspective View of one 01": the resilient connectors for the Overlapping encls of the jackets.

In carrying out the invention, 1 make use of :1 sheet 1 of suitable weatherproof material, such as leather, which is preferably of the shape iscleseii in F 3 but may be plane 01* tlie following descriprelation.

central clips in the manner shown, the ends of the sheet 1 being arranged in overlapping The narrower end of the sheet and pad 1S, of course, arranged near the adjacent end of the spring to insure a snug lit. As before intimated, I make use of novel resilient means for connecting the overlapping ends of the sheet and pad together. While this means may be of some other construction, I prefer to use coiled springs 3 for the purpose, the ends of these springs being extended beyond the. endmost convolutions and being bent to form anchoring hooks 4, the extremities of which are pointed or sharpened as indicated at 5 and adapted to hook into the sheet in the manner shown in Fig. 2. By employing these particular types of connectors, the jacket can .be drawn tight by hand before placing them in effective position and all wrinkles can be removed before each connector is hooked into the sheet 1. Thus, a snug fit of the jacket and a neat appearance is insured and wrinkling of the jacket is practically prevented. In addition to employing the novel spring connectors, I also make use of a pair of relatively long coiled springs previously referred to as anchoring means, these springs being designated by the numeral 6. Close examination thereof will disclose the fact that each one is permanently connected to one of the jackets and has at its free end a, hook7 which is designed to engage the adjacent end of the other jacket. In other Words, each jacket carries one of these coiled springs 6 and this sprin has its free end hooked into the other jac ct as disclosed in Fig. 4. ,It'is obvious as before. stated, that these springs 6 serve to prevent longitudinal creeping of the jackets and overcome wrinkling, but at the same time, permit sufficient longitudinal movement of the jackets to accommodate the relative movement of the leaves of the spring. While I have shown and described the springs 6 as having their free ends connected to one of the jackets, I wish it to be understood that these ends could be anchored at any suitable place on the spring if so desired.

In use, the pad 2-is saturated with a suitable oil or other lubricant and the jacket is wrapped around the springs on one side of the spring clips bringing the pad into direct contact with the leaves of the spring and permitting the ends of the outer waterprmf sheet to overlap one another the narrow end of the sheet and pad, of course, being dis- I posed at the adjacent end of the spring.

The jacket is drawn tightly about the spring by hand and'the pointed hooks of the connectors 3'are anchored or embedded in the" jackets, these connectors being disposed transversely of the spring in the manner disclosed in Fig. 2. It may be suggested that it will be well to place the connectors adjacent the ends of the spring in position first-and then smooth and draw the jackets tightly around the spring and place the remaining connectors in position from the end of the spring toward the center of the latter. In this way, wrinkling of the jackets can be practically overcome and a neat appearance insured. After the two ackets are in place, the hooks 7 of the springs 6 are connected to the proper jackets in order to prevent longitudinal creeping of the jackets.

It is hardly necessary to again direct atten tion to the fact that the employment of these i particular kinds of retainers or connectors overcomes the possibility of the jackets splitting or breaking since free relative movement of the leaves of the spring is permitted, which is not the case with the ordinary types of jackets now on the market. The jackets can be applied on the spring in little or no time and the person applying them need not be experienced in the least.

When the jacket is in place, it will insure 4 thorough lubrication of the leaves of the springand prevent the depositing of dust, mud, or other extraneous matter thereon.

In case the spring should become broken 'ivantagcs gained by. this particular construction and arrangement. Therefore, a more lengthy and detailed description is thought unnecessary.

Although advantageous and effective results are practically insured withtthe coir struction and arrangement herein shown and described, I wish it to be understood that slight changes in the shape, size, and arrangement of parts may be resortedto within the scope of the subjoined claims.

I claim:

LA lubricating and protector jacket for vehicle leaf-springs comprising a sheet of flexible weather-proof material. a pad ,t absorbent material securedto the inner face thereof and adapted to contain and dispeuse a lubricant. resilient means for connecting threads of said sheet together, and a re cket in me ve- Jnt anchor for ene end 0' 1e e emj Wrnidmg and io mulmal edgnbination Wits a leaf-spring for I of a pan of l )rlea' zmg 1nd pro thereeq 011 surfeee rafher snugly aroma zine ends arranged in everlapping relationship, coiled springs having their ends bent to provide hooks, said springs being errengei transversely across the jacket and he '1' their hooks engaged with file overleppe ends 0f said jackets to connect said ends iegether, but permii them to separate to aceommodete the reiaiive movements of the various spring leaves, and a resilient ancher the inner end of the jacket, serving to prevent wrinkling of the latter and to pre vent longitudinal slipeing thereef.

In testimony whereof I have hereunto set my hand.
